Free convection
 

Hello,

I am trying to simulate a case of free convection. To do so, I apply in 2D box 3 symmetry boundary conditions and a wall condition. At the wall, I impose only a sinusoidal temperature value. I use a K-eps turbulence model.

The model doesn't seem to converge properly (no convergence after 100,000 iterations). The velocities calculated are not coherent.

Can anybody help with this? What seems to be the problem here?

Thank you in advance.
